Make sure to have a long term investment plan, and while you invest and wait, you can trade actively on the side. Could be P2P or actual spot or futures/margin trading on the side to make little profits on the way up.
That's easier said than done. One can only hodl long term if one has a steady source of income and not the regular kind of invest today and then expect it to give a nice ROI overnight so one can harvest it. Another is your advice on trading. That's not an advice for newbies because trading is not an easy thing to venture into. The complexities of trading, whether spots or futures, have led so many who saw how simple it looks from far to burn their capital and went back to square one. Trading is a specialized field and should be given its due attention.
